For camping, has anyone used a Go Zero Yeti 400 to power a ResMed Airsense 10 Auto? The ResMed website states that an inverter should not be used to power this unit. Do you need to purchase a converter instead? Thank you for any help you can offer.
I am not familiar with this at all. When we go camping we usually have electricity so hooking up my CPAP is no big deal. I do have a friend that has looked into battery-powered machines but I have no idea whether it has been a fruitful search or not. Can you contact the Yeti people to ask them?
This is another subject for which I know nothing. I frequently camp in my RV but almost always on shore power (a bit ol' 30A AC supply!).
Here is a discussion of the subject you are interested in on another forum: http://www.cpaptalk.com/viewtopic/t114012/Choosing-a-Battery.html
I also know that ResMed sells a battery backup system that looks a bit lighter than then the Goal Zero Yeti 400 you mentioned. Of course, it is ResMed so it is a bit pricey: https://milwaukee.craigslist.org/hab/6114785991.html
Other manufacturers seem to make it easier to run straight DC so you might look at a different CPAP machine (if that is the mode your Airsense is operating in). Some offer an inexpensive direct DC power cord as an option.
No is the short answer, I have only ever used mine off mains power. Using the inverter puts the Resmed power brick at risk and they are expensive to replace.
Personally I would have thought converting a 12v dc source through an inverter to a 110v a/c back through a power brick into the machine not to be that dangerous but I have heard that inverters do cause trouble with some switches, relays, and in particular dimmer switches.
With Resmed stuff I would stick to their official product for the powering as I can imagine their power brick could be temperamental because my brother has had to replace one.
That is why I suggested another brand of machine. Some have 12V DC cords as accessories which means you just hook the electrical leads to a battery (AGM deep cycle type might be best) and the end is a cigarette type plug you plug the machine into. Given the cost of the Resmed solution, it might be cheaper to just buy a 12V direct-compatible machine and just use the Resmed at home.
ResMed has come out with a travel size machine that they are developing a direct DC cable for according to their website:
